APL is using Chinese technology while NTPC is using Russian and Korean super critical technologies.
Generally, a unit with more than 500 MW capacity is referred as supercritical. The technology has derived its name from use of supercritical pressure for generation of steam — which rotates the generator — by firing coal.
